Summary

Completed in 1945, this earth dam stands at a height of 16 feet and has a structural height of 19 feet, providing a vital defense against potential flooding events. With a normal storage capacity of 47 acre-feet and a maximum storage of 95.8 acre-feet, Randall Dam plays a vital role in managing water resources and protecting the surrounding community from the dangers of flooding.

Despite its importance in flood risk reduction, Randall Dam is currently classified as having a low hazard potential and a poor condition assessment, based on data from a 2017 inspection. While the dam is under state regulation and inspection, there is room for improvement in its maintenance and overall condition. With the dam located in Buffalo County, Nebraska, under the jurisdiction of the Nebraska Department of Natural Resources, there is a collective effort to ensure the safety and integrity of Randall Dam for the benefit of the local community and water resources enthusiasts alike.

As climate change continues to impact weather patterns and increase the frequency of extreme weather events, structures like Randall Dam play a critical role in safeguarding communities and water resources. With ongoing inspection and regulatory oversight, there is a commitment to maintaining and improving the condition of Randall Dam to ensure its effectiveness in flood risk reduction. As a key component of the water management infrastructure in Nebraska, Randall Dam stands as a testament to the importance of proactive maintenance and monitoring in the face of evolving climate challenges.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
